Technical Design STAM provides full support to Customers from preliminary to detailed design of electrical and mechanical systems in the following sectors: - Space - Aeronautics - Transport - Defense - Environment The staff has been involved in trainingand development related to dynamic simulation techniques, geometric modeling, parts and assembly models, dimensional optimization, and integrated mechanical design with a 3D Cad System. Recently Stam designed and assembled a test bench to perform the evaluation of the efficiency in different loading situations and with different input speeds of Nugear prototypes. Besides the test bench evaluates the smoothness of mechanical transmission as well as the performance in service,vibration and noise.
